Prudent Portfolio Update

I'm still working on the layout of PrudentPortfolio. I used one of Bloggers standard layouts and changed it up for my needs. I needed a wider column for my tables. Anyway, the site is at least up. I will update the portfolio on Friday afternoon or Saturday morning.

Surely there is a way to program a table to update itself. Does anybody know anything about this? I don't even know where to begin to learn about this. If anyone knows, please leave a comment or email me at AllThingsFinancial at Hotmail.com.
